There's a new craze in classrooms and it's all about spinning. Fidget spinners have become this year’s leading toy fad. Squeeze the core, give the blades a flick and let them spin. That’s it. They are between $3 and $4 and are available in all sorts of color schemes. Doctors have given the toy to children with anxiety or attention deficit disorder because being involved in this repetitive tasks allows you to free your mind. Now all the kids are hooked to it much to some teachers' chagrin.
